The list of A hundred Italian films to be saved was created with the aim to report "100 films that have changed the collective memory of the country between 1942 and 1978". Film preservation, or film restoration, describes a series of ongoing efforts among film historians, archivists, museums, cinematheques, and nonprofit organization to rescue decaying film stock and preserve the images they contain. In the widest sense, preservation assures that a movie will continue to exist in as close to its original form as possible.
